80-Series QoS
set port mask-diffserv Command Mode Global Configuration.
Description Sets a port to mask the three least significant bits of the DSCP when the
switch is using the DSCP to classify bridged IP traffic. If you mask the three
least significant bits of the DSCP, the switch recognizes the remaining bits
as the precedence field of the Type of Service (ToS) field and classifies the
packets accordingly.
